Title: Observing device for optical sampling wave-form
Inventor: OTA HIROYUKI
IPC: G02F1/37
Filed: 1996-11-27
Abstract: PROBLEM TO BE SOLVED: To measure a signal light, whose polarized state is fluctuated, accurately and independently of the state. SOLUTION: An optical multiplexer 2 multiplexes a signal light to be measured and sampling pulse light and makes the multiplexed light incident on a SF light generator 3. The SF light generator 3 consists of two kinds of non- linear optical crystal pasted optically. In the non-linear optical crystal (A), SF light occurs from longitudinal polarization component of measured signal light and latitude polarization component of sampling pulse light, and in non- linear optical crystal (B), SF light occurs from latitude polarization component of measured signal light and longitudinal polarization component of sampling pulse light. A basic wave removing filter 4 removes light other than SF light of output light from SF light generator 3. A light receiver 5 transduces the SF light into electric signal.  Electric signal processor 6 restores measured signal light on the basis of the electric signal. Display 7 shows wave-form of the restored signal light.

Title: Tunnel transistor
Inventor: UEMURA TETSUYA
IPC: H01L29/73
Filed: 1991-12-02
Abstract: PURPOSE:To operate a tunnel transistor at the ambient temperature by reducing an excess current and increasing a tunnel current. CONSTITUTION:An emitter layer 7 is formed of GaSb, and a collector layer 4 is formed of InAs. An energy of a valance band of an emitter is set higher than a conduction band of a collector, and an AlSb barrier layer 6 is inserted between both the layers. Further, the layer 4 is reduced in thickness to generate quantum levels E0, E1... An AlSb gate layer 2 is formed at an opposite side to the layer 6 through the layer 4. Since a current based on tunneling between resonance bands between the valance band and the conduction band flows between the emitter and the collector, a tunnel current density is increased, an excess current can be suppressed, and it can be operated at the ambient temperature. A quantum level is varied by a gate voltage to be applied to the layer 2 to control negative resistance characteristics.

Abstract: PURPOSE:To prevent the vibration of recording images by recognizing the central signal of the images in a central recognition circuit, controlling a conversion circuit so as to position this signal always at the center of the images to read the signals out of a temporary memory circuit in a control circuit and recording the signals in a recording circuit. CONSTITUTION:The recognition data of the image existing in the central range of the image recognized in the central recognition circuit 3 does no longer coincide with the recognition data of n-times before in the case of generation of the vibration. All of the signals stored in the temporary memory circuit 2 are read out at this time and are compared with the recognition data of the n-times before. The coinciding signals are then detected. If there is the signal coinciding with the recognition data among the signals stored in the circuit 2 as a result of such detection, existence position of the recognition data is transmitted as central data to the control circuit 6. The circuit 6 executes control so as to read out the recognized data as central data. The image data corrected in such a manner that the center thereof coincides the center of the n-times before is read out of the circuit 2 and is recorded in the recording circuit 5. The deviation in the images is eliminated in this way and the adequate recording is obtd.
